1 nAILWAY-TIn Specification of Letters Patent.

To all whom z't may concern.'

Bc it known that I, JOHN iV. CHAMrioN,

'citizen of the United States, residing at the city of Colorado Springs and State of Colorado, have invented certain new and useful lmprovcments in Railway-Ties; and I do oeclarethe fpllowing to be a full, clear, and exact description et the invention, such as will enable others skilled in the art to which it appertains to make and use the same. reference being had to theaccompanylng draws ings, and to the characters of reference marked thereon, which -form a part of this specification.

- The present invention relates to improvel ments in railway ties and pertains moreparticu'larly to ties made of rolled'metal.

The invention has for its principal object to provide an improved form of metallic tie \.'hiclrwill properly adjust. itself to the surrriface of the ballast or road bed and which `will 'further provide a strong and. durable railsnndcr the varying loads Support for the caused b v the rolling stock.`

A flu-therwobjec: of the invention consists in fr'irming the tie of two parts, namely,'a base plate and a main rail supportingbody portion. The first named part is so constructed as to engage the, surface of the road hed and prevent creeping' or lateral .displacemen t. The second part is adapted to be reeiliently supported on and attached to the base plate 4 sary expansion resulting from the depres sion caused by heavy loads passing over the rails. To accomplish this result a single horizontalbaseplate is provided having its 'lower surface roughened or corrugated and its lateral edges bent upwardly to provide tongues. The rail supporting body of the tie is formed in the shape of an inverted trough, having downwardly inclined sides, the lower edges of which are/provided with flaring lianges adapted to enter the inner sides of the tongues of, the base plate. An 4 interlocking relation of. the parts `is thus.

provided which, however, permits of sutH- cien-t play to allow the main bodyportion of tho-,tie to move vertically in relation lto the' base plate. l

NVith these and other objects in View the invention consists in the combination and arrangement jof `in the following specification, illustrated in -hase is provided thereby providing for the neces-v parts more fully set forth` the accompanying drawing and more p articularly pointed outin the appended elalm.

In the dra\vings:`

Figure l is a top plan View of one embodi- Inent otthe 4present invention. l Fig. 2 isa horizontal section taken on the line 2-4-2 of Fig. l

Fig. 3 is a transverse section taken on the lim` 3--3 of Fig. l drawn to a larger scale.

Fig. l is an enlarged fragmental view partly in section and partly in elevation of the invention` Fig. 5 'is a fragmento] perspetive ot' a detail showing the fastening means of one end of the tie.

Fig. G is la sectional manner of attaching according to the present invention.

Fig. 7 is a tra) plan view of the arrangement shown in Fig. 6, and

Fig. 8 is a detail of one ofthe rail fastenvieW showin one ing bolts detached.

eterrmg now to the drawlngand 'par-4 tical-arly to Figs. l and 4the tie comprises a base plate 5 and with a transversely corrugated surface 7 adapted toV engage the ground ballast or road bed and is vfurther pnivided at its oppositesides with upwardly bent porionsS vforming tonguespt'he pur-l pose of which will hereinafter appear. vThe rail'supporting body nicmlfer 6 is formed in the shape oi. an `inverted trough or U and'is provided with a pair of horizontally dih- Patented Jan. 15. 191s;

a rail to a metal ic tieV a body portion (i. The' posed depending, reinforcing Webs 9 at a pproximately eoual distancesfrom its transverse center. The sides-10 of the member incline outwardly and 4downwardly and terminato at their 'lower edges in a'ngularly benty outwardly extending flanges 11V adapted, as shown in Figs. 3 and 5, to extend into and be engaged by the upwardly bent tonguesl 8 formed at the sides of the base plate'. It will he noted that in positioniof the parte shown in Figg, which is assumed to the normal position without any load, .the flanges 1-1 do not entend clear into' the recess formed by thetonguesS; In order to firmly clamp the parts in interlocking relation with each other and prevent sidewise movementvof the parts the tongues 8 are slit "on a line 12 and the portion 13 isbent downwardly as shown in Fig. 5 contacting with the outer edge of the ange 11 of the Vniem- `are such that as a heavy load passes over the rails the member 6 is capable of bein depressed and the egxpansion caused there y is A'taken care of by a-slight outward movement of the 'anges 11 -within the grooves formed by the tongues 8. The corrugated surface of the base 'plate 5 gri s the ground firmly and in cases where allast composed 'of broken rocks or boulders is used the roughened surface will revent any side displacement of the base p ate in relation to the road Wely. eferring to Figs. .6, 7 and 8, one form of :the rail fastening means is shown. The upper surface of the rail sup orting body portionof the tie 6 is provi ed with pairs of slotted openings 14.

Each opening comprises a longitudinal slot having a cylin-a drical opening communicating therewith 'and formed nearer one end than the other.

slightly larger in diameter .of the attened portion thevbolt is retained and prevented from dropping downwardly.

The base plate of a rail 15 is placed transversely across the tie member 6 as shown `in Fig. 6 and there clamped in osition by means of a fastening device. A olt 16 such as .shown in Fig. 8 is provided with a cylindrical screw threaded stem vand a flattened head. A portion of the bolt stem ad'acent the head is also flattened and is of su cient width to enter the slotted opening 14. The head of the bolt'is inserted into the opening 14 and the bolt is then given a' quarter turn, the cylindrical `portion of the stem being than the width A. clamping member. .17 having a. portion adaptedv to extend downwardly into the slot 14 is then applied over the projecting stem oi. the bolt. This member 17 .is also provided xwith a forward-curved extension lug which overlaps and firmly engages the upper y surface of the flange of the base of the rail.

By applying the nut 18 to the threadof the bolt 'and lscrewing the nut down firmly against member 174, the clamping devices are firmly secured in .place. It will be noted that the cylindrical portion of the stein of the bolt 16 together with the downwardlyextendin portion of the clamping device '17 l clamping devices 17 can be removed is by raising them vertically upward until they become disengaged from the openings 14.

Having'des'cri-bed my invention what Il yclaim is:

A railway tie comprising'a base late providedwitli upturned edges and a ody portion having outwardly projecting flanges engaging said upturned edges in4 interlocking relation, the upturned edges being slit adjacent their ends and. the end'portions bent' downwardly to respectively engage` the end edges of the said flanges to prevent Isidewise movement of the parts.

A In testimon whereof I affix-my ,in presence o two witnesses.
